1. Don't try to put non-blower cards into a server chassis. They won't be happy, if they fit in the first place, even in 4U.
2. Relevant but not overly so, anything above x4 lanes should be enough to not make a huge difference in your performance. You should certainly always strive for the best possible, but as long as you have x4 lanes of at least 3.0, you should be fine.
3. This is effectively irrelevant and launching a CUDA kernel causes the drivers to automatically downclock your VRAM anyway, which so far hasn't had major impacts in the vast majority of hashcat's use cases.
4. Twice is a bit much, really the rule should be System RAM >= combined VRAM, but 2x obviously gives you a lot more room to breathe. System RAM speeds are effectively irrelevant and you likely won't even see _usage_ for a lot of it. The reason it's necessary is due to an allocation quirk in the runtime(s) i believe but these days it's a lot less of an issue. Sticking to system ram >= combined VRAM should be fine and avoid any issues.
If you want the "right" GPU to get right now, especially with the 4090 discontinued, look here: https://www.amazon.com/GIGABYTE-GeForce-...B0D87BVDWQ
